Can't get the best image quality! Help!

[#1]

Hello everyone,

I am creating an online-shop for my brand. Since the products are scarves, it is very important for me to have the best image quality.

1- First I resize the image on photoshop and save it as png

2- Then I open muse create a rectangular and select transform and paste the image into the box. (The box and the image has exactly the same size.)

3- when I click on preview, I see the big quality difference between the one on the website and the one on Muse.

Does anybody know why this is happening? Thank you so much!
